drm/sun4i: backend: Assign the pipes automatically
Since we now have a way to enforce the zpos, check for the number of alpha
planes, the only missing part is to assign our pipe automatically instead
of hardcoding it.

The algorithm is quite simple, but requires two iterations over the list of
planes.

In the first one (which is the same one that we've had to check for alpha,
the frontend usage, and so on), we order the planes by their zpos.

We can then do a second iteration over that array by ascending zpos
starting with the pipe 0. When and if we encounter our alpha plane, we put
it and all the other subsequent planes in the second pipe.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
